Vintage Costume Jewelry Designer Signed Necklace. Here is a very artful and well made necklace from the early 1950's. The Renoir name is on the clip. This item is heavy- bold and striking on. There are fifteen copper medallions held together with solid copper links.The medallions have a wonderful arts and crafts design with turned edges and are laden with multi colored enamel reminding me of the vintage 50s art glass ash trays and vases. The closure is a fish hook style. There is a metal backing on the medallions that gives the piece durability. This necklace is a great piece for the fall season . Excellent condition! 20" end to end.
